Market Samurai is a reasonably priced piece of software that can perform a number of research functions for
you. This video gives an overview of the tool, but it especially focuses upon keyword research.
The video was initially produced for the August, 2010 version of the 30 Day Challenge, but it is useful for
everyone.
This second video is a much lengthier (almost thirty minutes) overview of keyword research. The video
makes reference to Market Samurai being "in developement." That is outdated as the software is now available
for purchase by anyone.
